Few studies have reported the impact of telescoping flow diverters (FDs) in intracranial aneurysm treatment. Our study compared aneurysms treated using telescoping FDs to those treated with a single FD and identified predictors of telescoping. ⋯ Aneurysms with fusiform morphology, increasing aneurysm height and those that underwent flow diversion using Pipeline Embolization Device had higher odds for telescoping. Significantly higher rates of angiographic occlusion with the use of telescoping FD add to the literature on its efficacy in treating aneurysms of varying morphology.

Graft failure is a common complication of cranioplasty. Revision cranioplasty is required to overcome this complication. However, no previous studies have reported outcomes in revision cranioplasty with 3-dimensional (3D) custom-made titanium implants. We describe our experience with 3D titanium implants in patients with revision cranioplasty. ⋯ Initial cranioplasty with PMMA provides a longer time period than the AG before the revision. However, both of them have similar outcomes based on length of hospital stay and cranial defect area. Custom-made 3D titanium implant is a good option for revision cranioplasty to prevent implant failure and reduce patients' cosmetic concerns.

Surgical decompression is the recommended treatment for patients with nonfunctioning pituitary macroadenomas (NFPMAs) with associated visual impairment. Other relative indications for surgery include endocrinopathies, craniopathies, and headaches. Nevertheless, patients without these classical indications who would otherwise be considered asymptomatic with regard to the NFPMA and treated conservatively with clinical radiological surveillance may experience higher rates of other morbidities related to the NFPMA. We aimed to evaluate the prevalence of newly diagnosed comorbidities in conservatively treated patients with NFPMAs. ⋯ These results may suggest the advantages of early surgical intervention for NFPMAs to mitigate comorbidities and improve health-related quality of life.

Epidemiology of spontaneous subarachnoid hemorrhage (SAH) and unruptured intracranial aneurysm (UIA) is valuable for determining neurosurgical and general health care effectiveness. There is an information gap regarding these conditions in middle- and low-income countries. Therefore, we aimed to investigate hospitalization and mortality rates for SAH and UIA in Brazil from 2011 to 2019. ⋯ In Brazil, the SAH hospitalization trend is stable, although there is a worrisome increasing SAH-related mortality trend. A better scenario was observed for UIA, with an increase in hospitalizations and decrease in mortality.

The transorbital approach (TOA) has a unique advantage to the more common lateral approaches as it provides direct access to the anterior middle fossa and medial sylvian fissure (SF) without significant dissection or retraction. However, when to use the TOA for surgical treatment of middle cerebral artery (MCA) aneurysms remains unclear. This study details the feasibility of clipping unruptured MCA aneurysms via the TOA by highlighting the anatomic features that either facilitate or hinder the approach. ⋯ Given the minimally invasive, technically challenging approach, the feasibility and safety of TOA for MCA aneurysms must be evaluated before wide clinical adoption. This study identified AOF, aneurysm width, and SF accessibility as three features that may significantly impact the possibility of clipping MCA aneurysms via TOA.
